Premix burner according to some embodiments of the invention and gas-cooker are described with reference to the accompanying drawings。
As shown in Figures 1 to 4, the premix burner provided according to some embodiments of the invention, including main fire device 1 and igniter 2。
Wherein, as it is shown in figure 1, described igniter 2 is arranged on the side of described main fire device 1。
As shown in Figure 2, described main fire device 1 includes the housing of both ends open, the described opening of described shell one end is crater, the described opening of the other end is air inlet, described air inlet is connected with admission line, described admission line is provided with fuel gas inlet 151 and air intake 152, has the nozzle 153 connected with described fuel gas inlet 151 in described admission line, and the inner space of described housing is the premixer of combustion gas and air。
Premix burner includes main fire device and igniter, main fire device includes the housing of a both ends open, shell one end is air inlet and is connected with admission line, the other end is crater, and enclosure interior space is the premixer of combustion gas and air, and such combustion gas and air are through admission line, enter in the housing of main fire device from air inlet, then mixing in the premixer of housing, the gas of mix homogeneously overflows from crater, and the igniter being then within main fire device side will mix gas ignition。
In the illustrated example shown in fig. 2, the housing of main fire device includes upper shell 10 and lower house 11, and housing is divided into upper shell and lower house, it is simple to the installation of parts in housing。
As shown in Figure 2, described admission line is tee T 15, first end of described tee T 15 is connected with the described air inlet of described housing, second end is described air intake 152, 3rd end is described fuel gas inlet 151, and fuel gas inlet 151 place is provided with nozzle 153, notch setting is at 2/3rds places of nozzle 153 length, so, combustion gas and air can carry out first time premix in tee T 15, then enter in the housing of main fire device through the mixing gas of the combustion gas of premix first and air, and in the premixer of housing, carry out premix again, finally mixing gas overflows from orifice 12, and ignited device lights。
As in figure 2 it is shown, described main fire device is except including housing, also include: orifice 12, installing plate, porous plate 14 and multiple spacer body。
Wherein, described orifice 12 is positioned at described crater place。
Described installing plate is arranged on the lower section of described orifice, and described orifice is fixed in described housing by described installing plate。
As shown in Figure 2 and Figure 4, described porous plate 14 fixes with described installing plate, and the described premixer of described housing is divided into the first premixer and the second premixer, and described first premixer is positioned at the lower section of described second premixer, described porous plate 14 is provided with multiple passage 141。
Multiple described spacer bodies are arranged in described first premixer, and leave between adjacent described spacer body and be available for described combustion gas and gap that described air passes through, to change the flow direction of described combustion gas and described air, to make described combustion gas and described air mix in described first premixer。
Preferably, in embodiment as shown in Figure 2 and Figure 4, described installing plate and described porous plate 14 are integral type structure。Certainly, installing plate and porous plate can also be split-type structural, and now, installing plate and porous plate can be connected by screw or weld, and do not repeat one by one at this。
As shown in Figure 2, orifice 12 is positioned at crater place, it is provided with porous plate 14 below, porous plate 14, orifice 12 are fixed on the upper shell 10 of main fire device by bolt 16 and nut 17, and as shown in Figure 4, porous plate 14 form collecting tank 142, so, the residue produced after mixing gas combustion can fall in the collecting tank 142 of porous plate 14, will not pollute the miscellaneous part in housing, and be easy to cleaning。
The premixer of housing is divided into the first premixer and the second premixer by porous plate, it is provided with multiple spacer body in the first premixer being positioned below, and leave gap between adjacent spacer body, the mixing gas of combustion gas and air can pass through in the gap of spacer body, when mixing gas passes through in gap, constantly changing the flow direction of mixing gas, mixing gas can produce turbulent flow when change flows to, make mixing gas can not smooth flow, such combustion gas and air can mix in the first premixer;When mixing gas and entering the second premixer by the passage on porous plate, in different passages, the mixing gas of process meets in the second premixer and again mixes, and mixed gas finally flows out from orifice, and is ignited at crater place。
Premix burner provided by the invention, air and combustion gas have carried out repeatedly premixing in the first premixer and the second premixer, make air and combustion gas mixing in gaseous mixture body uniform, so, air does not enter premixer in order to the mode of high-speed rotational, reduce noise during burning and air and combustion gas mix homogeneously in premixer, improve efficiency of combustion。
A specific embodiment according to the present invention, as in figure 2 it is shown, be provided with two described spacer bodies in described first premixer, respectively the first spacer body 131 and the second spacer body 132。
Wherein, described first spacer body 131 is peviform structure, and is fixed on described porous plate 14 at the bottom of the basin of described first spacer body 131。
Described second spacer body 132 is tubular structure, and one end of described second spacer body 132 is connected with described air inlet, and the other end stretches in described first spacer body 131 from basin mouth, and just at the bottom of the basin of described first spacer body 131。
Specifically, as in figure 2 it is shown, described first spacer body 131 and described second spacer body 132 are all vertically arranged, and the basin mouth down of described first spacer body 131。
As shown in Figure 2, the premix burner that the above embodiment of the present invention provides, the first spacer body 131 and the second spacer body 132 it is provided with in first premixer, and both is vertically arranged, wherein the first spacer body 131 is peviform structure, and being fixed on porous plate 14 at the bottom of basin, be fixed on porous plate 14 by the first spacer body 131, fixed form is simple;Second spacer body 132 is tubular structure, its one end is connected with air inlet, the other end stretches in the first spacer body 131, and just at the bottom of the basin of the first spacer body 131, second spacer body 132 is connected with air inlet, such combustion gas and air can enter in the second spacer body 132 from air inlet, then enter in the first spacer body 131 from the other end of the second spacer body 132, the mixing gas of combustion gas and air is encountered after at the bottom of the basin of the first spacer body 131, adverse movement, and flow out from the gap of the second spacer body 132 and the first spacer body 131, subsequently in the first premixer, the flow direction of the mixing gas of combustion gas and air there occurs twice change (mixing gas flow direction in housing is as shown by the arrows in figure 2), when the flow direction mixing gas changes, mixing gas can not smooth flow, there is turbulent flow, make the combustion gas in gaseous mixture body and air mixing more uniform;Secondly, the setting of the first spacer body 131 and the second spacer body 132, make the flow path of mixing gas lengthen, mixing gas mixes in the process flowed, and the flow path of lengthening makes the mixed effect of mixing gas better;The mixing gas of mix homogeneously flows through the passage on porous plate, again mixes in the second premixer, and eventually through orifice 12 and from crater outflow, and lighted by the igniter of side at crater place。
